8 Claims. (01. 281-42) This invention relates to bookmarks and has for its principal object a bookmark device which .will mark the place in the book yet without being visible at the edges of the leaves when the bookis closed. Another object issuch a bookmark which will tend to automatically open the book at the desired page. Still another object is to provide a bookmark device which will have unusual advertising value for various commodities or purposes.

Other objects and advantages of the invention will appear in the following description and accompanying drawing. 7

Briefly described my special bookmark comprises a thin fiat spring-like device which is laid between the leaves. of a, book and which tends slightly to open the book at that point so that when the book is lightly held with the opening edge directed upwardly in a manner to encourage the leaves to open, they will open where the device was placedunder the influence of its spring. The device which tends to open may take any form froma pair of simple leaves hingedly connected together, to figure and formcut-outs of any desired shape, and they may be of any mate-. rial. Also in one form it may consist of a single leaf.

In the drawing Fig.1 shows in perspective an open book with one of my bookmark devices in place between the leaves.

Fig. 2 is a larger perspective viewof mydevice taking the form of a two leaf pamphlet died out and imprinted to represent a package of cigarettes. i

Fig. 3 is a substantially full size plan view of my device arranged in the'form of a two page menu, or other folder, and it also shows a page impaling spur, and variation in spring construction; Figs. 4 and 5 show respectivelyiside and" plan views of the bookmark died out in form of abutterfiy and modified features of construction.

Fig. 6 is a cross section of Fig. 4 as seen from the line 66 thereof. Fig. 7 is a side view of the device taking the shape of anathlete- Fig. 8 is a side view showing the device diedout to the profile of a mans head.

Fig. 9 is an enlarged vertical section of Fig.8 taken along the line 99 thereof- Fig. 10 isa plan view of a modified form of the two leaves 1, 1 as of paper, celluloid, cellophane, thin cardboard, or other material creasedand folded along the line 2 so as to open like a simple pamphlet, and threaded in and out of the two leaves thus formed is a thin fiat spring 3. This spring is like a piece of small clock spring and is also creased upon itself as at 4 to form a pair of opposed legs which are bent so as to tend to open outwardly and thereby open the leaves 1, 1' outwardly to the position shown in Fig. 9. These leaves are, in this showing, died out in the form of a profile of a human head, and the various de tails such as hair, ear, collar, etc., may be shown by slot-like cut-out portions 5 if the leaves are of colored cellophane or celluloid, or these details may be printed on the leaves. Y The form of the leaves may be varied almost without limit and in Figs. 1 and 3 they are shown as square cut leaflets, but in any event, when placed in abook and opened as the book 6 of Fig. 1, one of the leaves of the bookmark will usually be found standing up,sometimes almost vertically, depending on the particular bend of PATENT OFFICE the spring used, and the other will lie against the page. In this figure the leaf of the bookmark lying against the page is designated 7, the stand.- ing one 7', while the spring'is-designated-8.

In Fig. 2 the. construction is as described for Figs. 1, 8 and 9, except that the pair ofleaflets 9, 9 opened by the spring 10 is printed or lithographed to represent apackage of cigarettes and died out to show them, 11, projecting from the end of the pictorial package. The inside of the leaves is also imprinted to represent the cigarettes 11' withinthe package so that when openedbythe spring the contents of the package will be visible. Such an embodiment is best made with leaves of paper. 1

Fig. 3 shows a modification in which the leaflet consists of two leaves 12, 12 creased to fold at 13 and normally held partially open by flat springs 14, 15 which are woven in and vm tof the leavesthrough cuts made therein as in the previously describedfigures, though in this case the two springs are not joined as are the spring legs of Fig. 9 at 2, but they are separate so as to permit the leaflet to be'opened flat as indicated so that it may be printed within as amenu, Christmas card, advertising sheet, or whatnot. The two spring blades being arched outwardly will lie on one another when the leaves of the bookmark are'folded and tend to push them open and consequently also tend to push open a book in which the mark device may be inserted. Another feature of this construction is the provision of a small metal spur 16 which projects rearward and is crimped or otherwise fastened to one only of the leaves 12, or 12, as indicated at 1'7 and facilitated by a clearance notch 18 cut in the other leaf.

In Figs. 4, 5 and 6 the mark takes the form of a died out butterfly, preferably made of colored celluloid or the like having its two leaves creased along the line 19 and cut out to form the wings 20, 20' of the butterfly. The confronting curved springs woven in and out of the wings are shown at 21, 21. In this construction a spur is shown at 22 crimped or otherwise. secured to the folded edge 19 of the two leaves of the device. Such'a spur permits the device to be stuck into the crevice at the binding juncture of the leaves of the book in which the device is used, and also to be stuck to the coat or lapel of the person reading the book so as to be out of the way yet readily accessible to drop into the book just before closing the same. This spur 22 may be of any size and project at any desired angle.

In this construction certain advertising is indicated as cut-out of the wings at 23 and 23' and a further feature is shown which consists of forming oppositely turned hooks 24, 24 at the' extreme upper end of the device, either of which hooks may be hooked over the edge of the leaf of the book if desired. 7

In Fig. '7 is shown the application of the flat opening spring 25 when the leaves of the bookmark are died out to represent a figure as of a man or an animal, such as the athlete 26 depicted.

, In this case the two leaves are supposed to be onedirectly back of the other and with the two legs of the spring 25 running up the legs of the figure. While the examples show both leaves of the bookmark to be generally of the same contour or design, this is only for simplicity, as it is evident the leaves may represent different forms and be imprinted or surface marked in any way to carry out ornamental or advertising requirements. 7

In Fig. 10 the device consists of but a single leaf of material 27 which may be of any desired flexible material adapted to be imprinted with any surface matter, and woven in and out of the leaf along'one margin is a flat spring blade 28 and which spring may be bent in the form of a slight curve, as away from the observer in this figure, or sinuously back and forth, so thatwhen closed between the leaves of a book it will exert a slight eflort to open the bookat that point.

In any of the modifications the flat springs maybe held in place by crimping, or by an adhesive if desired, but practice shows that if simply woven in and out of slits in the leaves, their constant pressure against the leaves overcomes any tendency to shift.

Also to be noted is that with a naturally resilient material such as celluloid, or thin metal, for the leaves of the bookmark, it is sometimes possible to omit the springs entirely, though for permanent action the springs are much better.

folders with two or more leaves imprinted for business, advertising or sentimental purposes of every description, and I therefore claim:-

- 1. A bookmark comprising a plurality of leaves of sheet material arranged to open and close book-like and adapted to be compressed'flat between the leaves of a closed book, means carried by said bookmark tending to resiliently force its leaves apart and to normally retain said leaves disposed relatively in planes intersectingv each other at an acute angle, and said bookmark being removable from the book when the book is opened.

2. A bookmark comprising a plurality of leaves of sheet material arranged to open and close book-like and adapted to be compressed flat between the leaves of a closed book, and a fiat spring carried by said bookmark tending to resiliently force its leaves apart.

3. A bookmark comprising a leaf of thin material adapted to be compressed flat between the leaves of-a closed book, a flat spring secured to said leaf, said spring being normally bowed in one dimension in a manner tending to resiliently force the leaves of the closed book apart so that the book will more readily open at the point of location of the mark.

I 4. A bookmark comprising a leafof thin material adapted to be compressed flat between the leaves of a closed book, a fiat spring secured to said leaf by weaving back and forth through said leaf, said spring being normally bowed in one dimension in a manner tending to resiliently force the leaves of the closed'book apart so that the book will more readily open'at the point of location of the mark.

a 5. A bookmark as specified in claim 2, provided with a spur to engage a page of the book in which the mark is used.

6. A bookmark comprising a thin sheet of flexible material having associated therewith a strip of flat, resilientsheet material normally flexed one dimension and adapted to be compressed fiat between the leaves of a. closed book against the tendency of said strip -to assume its normally flexed shape thereby tending to open the closed book at the location of the mark in the book and the sheet of. flexible material being secured to the fiat strip and arranged relative thereto in a manner to correspondingly flex with said flat strip when the book isopened and closed.

'7.A bookmark comprising a pair of flexible leaves of sheet material joined together along an edge to open like a book, one of said leaves being bowed from its point of junction with theaother leaf outwardly .andaway from the other leaf, and means on the bowed leaf arranged and adapted to yieldably retain said bowed leaf in its bowed shape, said book mark being adapted to be concealed betweenthe leaves of a closed book between the leaves of a closed; book against the tendency of said sheet to resume its normally bowed shape thereby tending to open the closed book at the location of the markgin the book.
